Determination of Viability
When both the concentration of non -viable cells and the total concentration of cells
are known, it is possible to calculate the viability (%viability) of the cells or the
concentration of viable cells. For the calculation the multiplication factors must be
taken into account, which is the total dilution of the original sample, as in the
equation shown below.

%viability:
The percentage of viable cells in the origina l cell suspension

:
The total concentration of cells in the NucleoCassette (the displayed
result of the total cell count)
C
nv
:
The concentration of non-viable cells in the NucleoCassette (the result
displayed when counting the non-viable cells)
M
t
:
The multiplication factor used for the total cell count, e.g. the dilution
of the sample with diluent and lysing reagent
M
nv
:
The multiplication factor used for the counting of non -viable cells, e.g.
the combined dilution of the sample by diluent
